Gripper Plates

Geofoam Gripper Plates

Galvanized steel gripper plates are used between layers of EPS geofoam to restrict lateral movement between layers. Typically 2-3 gripper plates are used for every 4' x 8' block or sheet. The gripper plates have barbs on both sides that bite into the layer below and the layer above to restrict or eliminate lateral movement. They are installed by pressing the 4" x 4" plate into the layer just installed and them pressing the next layer of geofoam into the upward protruding barbs.
